Fixed: install() and uninstall() doesn't work with arguments
Fixed: install() and uninstall() doesn't work with arguments

the argument of self.run_cmd() must be either a single string containing
all the cmd arguments or a sequence of cmd arguments. In install() and
uninstall(), arguments might be sent as something like:
['install -l -r', pkgapp] or ['uninstall', '-k ' + package]

These kind of arguemnts will fail to run.
